The bamboos {{#invoke:IPAc-en|main}} are a subfamily (Bambusoideae) of flowering perennial evergreen plants in the grass family Poaceae.

Giant bamboos are the largest members of the grass family. In bamboo, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.<ref>Botany; Wilson,C.L. and Loomis,W.E. Third edition.

Bamboos are the fastest-growing plants in the world,<ref name="Farrelly">{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> due to a unique rhizome-dependent system. Certain species of bamboo can grow 91 cm (3 ft) within a 24-hour period, at a rate of almost 4 cm (1.5 in) an hour (a growth around 1 mm every 40 seconds, or one inch every 40 minutes).<ref>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick, or concrete and a tensile strength that rivals steel.<ref>The Bamboo Solution: Tough as steel, sturdier than concrete, full-size in a year.

The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>
